Abstract
A method for the friction welding of parts and a holding device for at least one of the parts during the friction welding are disclosed. For the torsion-proof holding of the part in the holding device, regular positive-connection faces are provided therein. Corresponding positive-connection faces are fashioned in the region of the holding face of the part, such that the part can be retained in the holding device in a positive, torsion-proof manner. So as avoid forming the positive-connection faces located on the parts in a separate operation, these faces are produced only during the execution of the friction welding by utilizing the axial pressing force via an embossing operation carried out by the positive-connection counterfaces formed in the holding device and made cutter-like. For this purpose, the positive-connection faces are arranged in close succession in the form of a ring at an acute angle of less than 45.degree. to the axial force direction, so that they can dig in a force transmitting manner into a peripheral workpiece edge located on the parts.
